					LEAD
Why are we worried about lead?

   Protection of children primarily
       Most buildings are open to the public,
        i.e. “Public Buildings”
       Workers could take dust home on their
        clothes, creating exposure to family
        members


   Protection of workers/occupants
       Workers and occupants could get
        exposed via inhalation/ingestion of lead
        dust
Lead Facts
Lead can be found:
 Paints and coatings up until 1980. Industrial
  paints still contain lead in high levels.
 Printing equipment
 Batteries
 Plumbing
 Soil
 Water
 Imported food
 Imported medicines and cosmetics
 Radiation shielding
    Lead Hazards
   Children, Pregnant women & developing
    fetuses most at risk of harm from exposure

   Lead is readily absorbed and distributed.
    Collects in the brain, bones, teeth and organ
    tissues.

   Lead overexposure can lead to damage to:
       Nervous system
       Kidneys
       Blood-forming system
       Digestive system
       Reproductive system
Additional Effects on Children

   Brain damage
   Behavior and learning problems
   Slowed growth
   Hearing problems
   Headaches
Children more at risk of lead poisoning
due to:

   Nervous system sensitivity
   Absorption levels
   Pica: putting toys, hands, etc. into
    mouth
Lead exposure routes

   Hand to mouth contact with lead-
    contaminated:
       Dust
       Soil
       Water
       Other products


   Inhalation of dust and fumes
Lead poisoning
   Checked via blood test

Children/pregnant women:
>10 microg/dl - elevated
>20 microg/dl - lead burdened

Adults:
> 40 microg/dl - elevated
    Lead regulations
Activities related to disturbance of lead are
regulated by:

   Department of Health Services (DOHS):
    Housing and Public buildings
       For operations involving lead at 0.5% content

   Federal and Cal-OSHA: Worker Safety
       Operations that involve lead in any detectible amount


   Federal and Cal-EPA: Hazardous waste
       For waste containing lead equal to or above 1000 ppm
        lead
What is being done to prevent lead
exposure to employees?

   All surfaces and materials to be
    disturbed are sampled and analyzed
    for lead content.
   Lead-containing materials are
    handled by certified employees and
    contractors
   The campus drinking water is
    regularly tested for lead.
OSHA requirements

Include:
 Proper work techniques

 PPE

 Worker training

 Medical monitoring
Prevention of exposure to University
community…


   EH&S reviews all repair/remodeling plans

   EH&S determines if work can be
    completed in-house or if an outside
    contractor is required.

   Facilities Management Project Managers
    are provided with training
In-house lead disturbance

   Must be reviewed with Office of
    EH&S to develop work plan, ensure
    worker and occupant safety and
    collect worker exposure sampling.
Employee/Supervisor
Requirements

   Building Materials must NOT be
    disturbed without authorization
    from EH&S
